During the summer of 1981, a research project was initiated to monitor strains and deformation in 84-inch diameter RPM (reinforced plastic mortar) pressure pipe. Three 20-foot (6. 1-m) long sections of pipe were instrumented with strain gauges, temperature gauges, and measurement points. Strain, temperature, and deformation measurements were taken at various times during construction and after completion of construction. Results indicate highest strains in the pipe occurred near the midspan of the barrel of the pipe at the invert in the hoop direction. Strain concentrations in the invert are attributed to installation conditions.
